This is an American version of Shepherd’s Pie. Traditionally Shepherd’s Pie would be made with ground lamb or mutton. This is technically considered a Cottage Pie since it is not made with lamb. Most American’s call either version Shepherd’s Pie and aren’t usually sticklers on the traditional name.

Shepherd’s Pie is perfect for using up leftovers, you can use almost any leftover meats, potatoes, gravy and vegetables. I made this with Leftover Pot Roast and gravy made from the roast drippings. If you don’t have leftover roast you can use browned ground beef, lamb, turkey or pork. If using ground meat you will probably want to add some extra seasoning. I would add Worcestershire sauce and garlic pepper to taste.

This dish can be prepped ahead of time and refrigerated for up to three days before baking. You may need to extend the cooking time for 5-10 minutes when cooking from a refrigerated state.

I used a mixture of white and orange cheese, cheese is optional. If you don’t want to use cheese you can just brush the potatoes with a little bit of butter before baking.

As you can see I filled my pan a little too full trying to use up as many leftovers as I could. Luckily I could tell it was too full before I baked it. I placed a cookie sheet underneath the casserole dish, so no messes in the bottom of the oven, yeah!
